First I empty my bowels. I wait about a half hour and then douche, maybe 2 rinses because the expelled water is still dirty. Usually on the 3rd rinse I get even more "debris" than before! I always have sort of a messy session with my (non-aneros) toys. Whats wwwwrong?

You could be using too much water and cleaning too far up. You also need to make sure that all the water is expelled because if not yes your sessions will get messy especialy when you pull out the aneros as it is like pulling out the plug and all kinds of muck can just come out.

Experiment with the amount of water, everyone is different.

The other thing is lube your dirty sessions could be you are having a reaction to your lube. change and see.

You may have a problem with the nature of your stool. If it is firm there should be no residue and douching becomes largely a formality. If your stool is loose and tending to be liquid, it is sure to result in a messy cleaning out.

I would agree with @ineverknew, you probably need to increase the amount of fibre in your diet.

@wontquit. How much water are you putting in. Somewhere amongst the posts there was a suggestion to limit the amount so it does not pass through the third sphincter, if it does it will release matter from the descending colon (enema). You can see I am not medically trained. Also I personally find any quantity of water based lubricants also seem to stimulate early release into the anal canal.

I have the same issue sometimes (only with one of my non aneros toys), it is quite annoying. With my aneros toys I do a little cleanout and I am fine - if there is residue its plugged and not nearly enough to come out if I take it out slowly and carefully (never have had issues). Even playing with my Njoy Fun Wand the beads are small enough and the bulbous end doesn't have to go far to please my prostate, so I never have issues there either. The problem arises when I decide to play with my Tantus General...the thing is huge, long and wide so it just opens me up. I feel that it just goes so deep and widens my hole so much that it kinda digs out and loosens up whatever's way up there. So what happens is that some time into the session I'll basically feel the stuff waiting to come out, pushing against the dildo to the point where it's a hindrance and i'll have to keep myself plugged as I waddle to the toilet and expel the residue (sphincter's not gonna hold anything by itself for several minutes after I take the toy out). Sometimes this may happen a couple of times (sometimes it's my imagination too), but basically I have to be exceedingly careful if I am "riding it" so as not to have the dildo slip out (with disastrous results) or even pulling it fully out regardless of position so as to reinsert, doing it slowly making sure my muscles are not "pushing" else I risk a shitsplosion.

When I am playing with my General I always take extra time cleaning out (up to an hour! with repeated rinsing to be as thorough as possible. But still even when I feel I have been cleaned out thoroughly and no more water/feces can be pushed out, sometimes I just find myself interrupting my play session to expel more which makes me feel unclean (often wanting to rinse more water through it, having to re-lube afterwards further disrupting my session). Of the 7 months I have had this dildo and roughly 15 sessions playing with it, I have had one session where I suppose I must have luckily cleaned out 100% because I just kept going until I was fully satisfied and finished and even after that there was nothing to spill out except excess lubricant.

I feel I have a well-rounded healthy diet and pride myself in that so (I could be wrong) but I don't feel it's so much an issue of fiber. I'd love to know of any techniques out there to further ensure that I get everything out prior to starting.

Heh speaking of I just had an awesome session with my General dildo. After being revved up from an incredible helix session last night, I was more in the mood for a hands-on session tonight. I did a quick cleaning beforehand lasting no more than 10 minutes, about three rinses as I planned on playing with my Njoy Fun Wand. Well I did for about 30 mins then I really just felt like going for the dildo as I was nice and loose anyway. Well that went on for almost an hour and nothing but crystal clear lubricant, it was like the cleanest asshole I ever had hahaha. It was absolutely perfect, I guess I got lucky - a tiny amount was expelled during the cleaning but besides that I hadn't passed a bowel movement since earlier in the afternoon. Or perhaps braveneworld has a point with overdoing it and cleaning too far up! Something I will have to take into consideration for the future.

Ok after another awesome long session with my tantus general, I'm willing to conclude (from these two trials) that the problem was indeed using too much water too far up. I just need to not empty the whole pump, and limit it to just 3-5 rinses to get everything out and clean. Thank you so much for the input! It was frustrating having to worry about that, but now everything is as it should be :D.
